Second, in the construction of the frame and means for securing the sameto the barrels;

Third, in the locking means for the breaking down mechanism throughwhich the spring is compressed; i

Fourth, in the construction of a safety device; A Fifth, in otherfeatures as will be more fully hereinafter set forth.

My impro-ved gun is ofthe typev comprising an outer or false barrelwithin the forward portion of which are arranged the shooting barrel andshot magazine. 'I'hese features are not, however, a part of the presentinvention and, therefore, will not be described in detail.

A and A are the false barrels of the double barrel gun having arrangedintermediate the same the rib B. The latter is preferably formed of asingle blank having a. flat top rportion B .andoppositely turnedsegmental side'portions the anges C by spot-welding at distributedpoints. It also has a portion D extending rearward beyond the rear endsof the barrels for pivotal attachment to the stock. This stock is formedof the wood portion E and the metallic portion F secured thereto, thisbeing a member of inverted U-section which embraces the portion D of theframe and is also fashioned to close the rear end of both barrels. Thepivotal connection between the stock and the member D' is preferablyformed by aligned annular 20 flanges F' projecting inward from theopposite sides of the member F and engaging corresponding apertures inthe member D. A clamping screw G extends through these flanges andacross the members D and F, serving to holdthese` parts together Ibutthe pivot bearingis formed on the anges. The stock is normally locked inalignment with the barrels by a U-shaped member H rockable on a pivotpin H extending acrossl the member F, and having at its lower ends latchhooks H2 forI engaging inturned ears D2 on the portion D. A-flat springH3 attached to the member H and bearing against the top of the member Fserves to yieldably press the latch hooks H2 into engagement with theears D3, thereby elfecting the locking. The releasing of the lock isaccomplished by a lever I pivotally attached to the upper portion oi themember F and having `extending inside the latter the crank arms Iadjacent to the top portion of the. member H which is above the pivotH2.` Thus, when the lever I is moved from its central position to oneside in either direction, the crank arms I will rock the member Hsuiiiciently against the tension of the spring H3 disengaging the latch45 hooks I-I2 from the ears D2.

Within each of the barrels A and A is secured an abutment J for limitingthe forward move- Ament of the piston J which compresses the air forfiring the projectile. This piston together '5g with its tubular forwardextension J2 passing through the abutment J and entering the firingbarrel, is similar to constructions heretofore used and need not Ibefurther described. In rear of the piston is a tubular shank J3 having abi- 55 furcated portion J4 terminating in enlarged ends J5. Betweenthese end portions are members J6 which are secured theretol byoutwardly projecting lugs J7 passing through apertures in the portions J5 and riveted at their outer ends. The members J 6 have downwardextensions J2 which form the hooks for engagement with the sear ashereinafter described. A spring K surrounds the shank J3., its forwardend abutting against the piston J and its rear end against a stop orabutment K. he latter is formed with a tubular portion K2 which fitsWithin the barrel and downwardly extending ears K3 notched at K4 teengage a cross pin K5 secured in the forward end portion of the frame D.Thus the thrust of the spring will be taken by the tubular 4portion K2and transmitted through the ears K3 to the pin K5 and finally to theframe.

The springs for the plungers in both barrels are simultaneouslycompressed by the breaking down of the gun through the followingmechanism. L is a link pivotally attached at its rear end to a crosskpin L' in the member F and having at its forward end a T-shaped headL2, which simultaneously engages the depending members J8 of the.plungers for both barrels. Thus, whenever the gun is broken down, thislink will draw the plungers rearward to compress the springs K. Beneaththe link L there are arranged in the frame D adjacent to each other apair `of sear members M, each of which is of an inverted U cross sectionand which pivotally engages a cross pin M. The rear ends of these Searmembers are notched to form the locking shoulders M2 for engaging withthe depending portions J8 of the corresponding plungers. A tortionspring M3 mounted upon the pivot pin M serves to yieldably move themembers M upward so as to force the same into locking engagement withthe members J2, as soon as the latter have passed the shoulder M2. Eachsear is released by a trigger N, both triggers being p-ivoted upon across pin N' and having forwardly extending bell crank arms N2 forengaging the sears M to depress` the same. Accidental operation of thetriggers is prevented by a safety member O which is slidably mounted ona guide member P. This member P forms a partition extendinglongitudinally and centrally of the frame D between the sear members Mand triggers N, being welded or otherwise attached to the bottom of theframe. The member O has a rear portion slidable on the top ofthe memberP and a bifurcated forward extension, the furcations O of which are onopposite sides of the member P and the triggers N adjacent thereto.Between the furcations O" ist a downturned portion O2 slotted to embracetheguide P. 'I'here is also a transversely arranged return-bent portionO3 which engages a slot P inthe member P and holds the member O againstupward movement. A downwardly extending portion O4 on one of thefurcations O' passes through a slot in the bottom of the frame and formsan operating member. There is also a downturned portion O5 which isadjacent to the rear edge of the member H. The construction is such thatwhen the member O is in its rear position the portions O2 on theopposite sides of the member P will extend into the path of a rearwardlyand upwardly extending portion N3 of each trigger, so as to form a stopfor preventing trigger movement. On the other hand, when the member O ismoved forward by means of the operating member O4, the portions O2 willbe out of; registration with the portions N3 permitting free actuationof the trigger. A latch spring O5 secured to the member O and engageablewith notches P2 and P3 in the upper edge of the member P serve toyieldably hold the member O in each positon of adjustment. It is,however, desirable to automatically control this safety device so thatwhenever the lever I is operated to release the lock of the breakdownmechanism, this will adjust the member O into safety positon. Suchoperation is accomplished by the rocking of the member H against theportion O5 whenever the lever I is operated to disengage the hook H2from the ear D2. Such rocking will move the member O rearward intosafety position where it will be retained by the latch spring O6 untilmanually released by movement of the operating member O4.

It is usual to provide guns with a hand` hold upon the barrel which Ihave formed of a wooden member Q fitting beneath the barrels A and A inadvance of the frame D. The rear end of this member has a tongue portionQ which is inserted within the forward end of the frame D, and theforward end portion is fashioned to fit around between the barrels. Forsecuring it in position a bridge strip Q2 is welded or otherwise securedto the two barrels and has a threaded aperture therein for engaging ascrew Q3 -passing through the member Q. Thus, when the screw is fastenedthe handle will be rigidly held in position.

A gun constructed asabove described, can be manufactured at low cost; iseasily operated, and is automatically placed in safety when in loadedposition.
